Additional Comments: Hello everyone, I am looking to build my first computer. It will be used for gaming. I have not picked out any parts that I need, because I want to see what you all think would be good. My budget is $600 but I would push it $650 MAX. I will be playing a variety of games such as WoW, BF3, AC3, Diablo 3, and other newer games. I live in the US if that helps any. Any help and advice on building is greatly appreciated. Thanks!

I was just wondering! and thanks a bunch. It looks like a good build. I hate to sound like most of the newbies asking the same question, but do you have any advice or suggested sites to learn more about building and hardware?

Look up Carey Holzman and his gaming pc tutorial on Youtube. He goes more into depth then any other youtube guide I've seen. Also, Newegg has made a few good ones, but Holzman seems to be more knowledgable then the guy who runs NeweggTV.

Cballs build is basically right on the money, except that 650ti is way overpriced. You've got the money for a much more powerful card - swap that out for a 7850 1gb and you will be much happier. Watch this page http://pcpartpicker.com/parts/video-card/#c=81&sort=a5, and slickdeals.net - while today I can't find one for less than $165, ($170 if you don't have shoprunner), you won't have to wait long to get it for the $160 or less the 650ti is listed for above.
